What is right method to pass led info from processing to arduino

[kll]

so,
atoi of that string might be not the right idea.
and yes, that might be the most efficient protocol for this
but can never be used via a terminal ( they all ascii )
and actually i prefer the complete opposite way to do communication:

Good practice for sending data from Arduino to Processing

there are many ways, but for datasets i use CSV style, 1024,1024,1024,1024, per line what actually requires good documentation what data is what sensor… and it is faster insofar as the line sending and line catching via serial/USB ( you would send 4 lines ) takes more time as the string separation. ( your way also needs that value decoding… ) but there are many other way, the fastest still would be a byte stream ( not ASCII ) but i hate, as i can not read it in Arduino IDE terminal t…
